Roamer, I tried to transfer money between accounts while I was in PI recently. The software recognised the IP and sent a security code to my mobile phone, which I didn't have with me. Best to let the bank know just to be sure.

With Halifax I`ve never had any problem, I set up my Thai Kasikorn bank account as a payee whilst still in the UK, no problems with transfers.
I did however inform them quite some time ago that I would be spending a lot of time in Thailand.

With Santander, it appears they are able to detect different ISPs, has caused occasional problem,sometimes have to go through extra security.

I`d with Fork, let them know and maybe bring your UK phone ( or SIM) with you in case they need to contact you ?

Tor is a server that hides your location. I read about it one night. Absolutely fascinating. It's how you get to the 'deep internet' where wiki leaks was originally and can do all sorts of shady untraceable things online. If you google the Tor Project or deep internet it's interesting reading.
